Yemi osinbajo swears in walter onnoghen as the chief justice of nigeria #comments

I think there may be a mistake here.

Yemi Osinbajo is the Vice President of Nigeria, not the President, and he does not have the power to swear in the Chief Justice of Nigeria.

Walter Onnoghen was actually sworn in as the Chief Justice of Nigeria by President Muhammadu Buhari on March 11, 2017.
